To all whom it may concern:

Be it known that I, ANDREW F. Hown,

tain new and useful Improvement in Fillet- Making Machines, of which the following is a' full, clear, and exact description, such as will enable Others skilled in the art to which it appertains to make and use the same, reference being' had to' the accompanying drawings, forming part of this specification, in which' Figure 1 is a side elevational viewof my improved fillet making machine. Fig. 2

Fig. 5is a detailed view of the planer cuttinghead. Fig. 6 are conventional illustrations of the different cuts made in producing a fillet.

This invention relates to a new and useful improvement in fillet-making machines, the object being to construct a machine ofthe character described which will be simple and cheap and which will enable the con sumption of scrap lumber in the production of finished fillets.

My improved fillet making machine is combined with a joiner as it is called,

which is a planer cutting head mounted under adjustable tables and a circular saw,

both of which are useful for other purposes than fillet makingmmachines which are generally emplo ed in a pattern and other wood working s ops.

In the drawings: 1 indicates the casing constituting a frame in the lower part of which is an electric motor 2, a pulley 3 on whose armature shaft drives a belt 4 passing around a pulley 5 and over a pulley 6. Pulley 6 is mounted upon a shaft 7 upon which is a planer cutting head 8. On

each side of this head 8 are tables 9 mounted upon inclined ways vertically and longitud'inally adjustable by means of hand wheels 10 cooperating with threaded rods conn'ected to move said tables in the manner well known. On the shaft 7 is also a cir cular saw 11 which operates through the bottom of the V-shaped groove or angle,

whose faces are approximately 90 de ees to each other, so as to serve as a gui e in diagonally. bisecting the strips in the pro-v overlapped in their cutting Serial No. 631,380.

duction of fillets.

be used for other purposes, such as pro-. ducing the rectangular strips A shown in Fig. ,6 when it'is desired to make fillets. The saw 11 cooperates with a shoulder12 mounted on a bracket casing 12 bolted to the framing 1 and preferably vertically ad.-

justable for Well understood purposes. .When the rectangular fillet strips A are made, they may be planed on the cutter head after which they are diagonally bi-- sected to form the triangular strips B. These triangular strips are arranged in a Patented May21, 1912.

This saw 11 may also- V sha'ped trough'13 and'fed by hand to a cutter head 14 mounted on the shaft 7. This cutter head is preferably made by stamp mg two plates from sheet metal so as to produce separate cutting blades whose cutting edges 14* are radially at a greater distance from the axiso'f rotation than the heels 149 of said cutter blades. There are two of these dished cutter plates oppositely arranged on the shaft 7; and being spaced apart by washers, as shown in Fig. 3-and clamped against the shoulder of said shaft by means of a clamping bolt shown. The

baldes of these plates are preferablystaggered with relation to each other and are'slightly paths, so.as to form the concave faces of the fillet. -When the strip B is fed to the concave cuttet, the fillet is formed as shown at C, Fig. 6, after which the lower angular back .of the fillet passes over cutting blades 15 mounted on the end of the shaft 5 upon Which'the pulley 5 is mounted. These 'cuttingblades 15 cooperate with washers and a clamping nut as shown in Fig. 4 and'are designed to increase the angle at the backof the fillet, as shown at D, Fig. 6. The purpose of this is to provide a clearance at the joint where the fillet is used, so that whenthe strip is placed in position in a corner of a pattern, it may be seated properly without the interference from glue or roughedges possibly left in such corners.

To hold the strip B in position as it is fed to the cutter 14, I provide a fiat spring v 16 whose pressure is exerted upon the flat upper face of the fillet, while a spring 17 preferably with a-curved-lower edge torfit in the concave face of thefilietis' p'rovided on the opposite side of the cutter 14 tofhold the fillet in a trough as it leaves the cutter 14. The trough; 13' is interrupted in its length so that the cutter can properly optrough 18, fillets of different sizes may be made. In desiring to maintain the relation of the trough to the cutter 15, it is obvious that the trough 13 could be pivoted upon the shaft 5*, but I have found in practice that the range of adjustment of the trough for different standard sizes of fillets is so small that the changed relation between the trough and the cutter 15 will not materially affect the operation of the said cutter upon the back of the fillet.

In Fig. 5 I have shown a planer cutting head of approved form for use in connection with my improved machine in which 21 indicates the body of the cutter head formed with longitudinally disposed recesses Whose Walls converge toward the periphery of the cutter head. In these recesses are inserted the cutting blades 22, said blades being held in position by wedgeshaped blocks 23, said blocks being forced outwardlyby screws 24 whose tapered inner ends cooperate with the inclined rear edges of the blocks. The blades are adjusted in their desired position and the screws 24 are employed to force the wedges outwardly to lock the bladesin place.

What I claim is:'

' In a fillet making machine, the combination ofjan' adjustable V-shaped trough for supporting the fillet blank to be operated upon, a cutter head fixedly mounted to one side of the pivotal point of the trough and located abdve said trough for grooving the face of the blank, and a cutter head mounted so as to operate upon the rear faces of the fillet blank to increase the angularity of the relation of said rear faces to each other.

In testimony whereof I hereunto aflix my signature in thepresence of twowitnesses, this 2nd day of June, 1911.,
